In the spirit of Halloween, add a few ounces of blk (pronounced B-L-K) fulvic-enhanced all-natural mineral water to your spiked elixir for a dramatic, festive effect. It is just water and when you use it in a cocktail you have to use a considerable amount to keep your cocktail dark. Keep this in mind when experimenting with drinks so that your cocktail doesn't literally become watered down. Try using darker spirits like dark rum, bourbon, coffee liqueur, or even jeagermeister. I've also frozen blk water before, which produced cool looking ice cubes that are dark on the bottom and clear on top.
